chore(deps): pnpm dedupe rolldown-plugin-dts peer-set drift

CI's Lint→Deduplicate step caught another mismatch where
rolldown-plugin-dts had two peer-resolved variants in the lockfile
(one with `oxc-resolver`, one without). The previous local dedupe ran
before this drift surfaced; rerun resolves it.
